To find the MAD(Mean Absolute Deviation):
1.Find the mean
a.add the numbers together
b.divide by the number of numbers given
2.Find the absolute value of the differences between each value in the data set and the mean
a.subtract the mean from the numbers in the sample
3.Find the average of the absolute values of the differences between each value in the data set and the mean
a.add the absolute values of the differences[from above step] together
b.divide by the number of data given[as like step 1]
